IRVIN D. LENGEL, F READING, PENNSYLVANIA, ASSIGNOIR TO KNOLL MANUFACTUR- ING COMPANY, OF READING, PENNSYLVANIA, A. CORPORATION OF PENNSYL- VANIA.

WAsHINe MAoHINn.

Application filed. February 21, 1325. Serial No. 10,773.

To all whom it may concern:

Be it known that I, IRVIN D. LENGEL, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification.

This invention relates to improvements in washing machines and the object in the present instance is to provide a mechanical movement, whereby the rotary movement or motion of the power shaft is converted into an oscillatory movement, to the end that the agitator, carried by the oscillating member will be given the proper movement.

The invention consists broadly of a power shaft having a crank thereon and an oscillating shaft also having a crank, and a pair of blocks carried by said cranks each of which is slidably mounted 011 opposite sides of a cross-head, which cross-head is provided with a pair of positioning links, whereby the rotation of the power shaft will cause the cross head to move in an are thus producing the desired movement of the agitator.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawings, in which Figure 1 is a plan view of the machine 'frame, showing the movable parts of the device in dotted lines and at one extreme position. Figure 2 is a central sectional view through XX of Figure 1. Figure 3 is also a plan view, similar to Figure 1, but showing the parts in central position.

Figure 4 is a horizontal sectional view of the casing and the entire mechanism within it. Figure 5 illustrates the relative positions of the mechanism and the agitator in the tub of the washing machine.

The numeral 1 designates the casing within which the mechanism is mounted, and which may be suspended below the tub in any suitable manner. 2 designates the power shaft and this shaft carries a crank 3 adapted to rotate with the shaft. On the end of the crank is located a sliding block 4 adapted to slide in the groove 5 in one side of the cross-head 6.

The numeral 10 designates the agitator shaft which also is provided with a crank on its extremity, 11, and this crank also carries a block 12 ,slidable in the cross-head,

on the side opposed to the one in which the block 4 slides.

The cross-head is formed with two oppositely projecting arms 15 and the ends of these arms are pivotally secure to a pair of positioning links 16, whose opposite ends are in turn pivotally mounted on the frame or casing, at the points 17 It will therefore be noted that, when power is applied to the shaft 2 its rotation will cause the crank carried by it to rotate, and the block 4 carried in the end of the crank will slide in the cross-head. This movement will cause the cross-head to move, but by reason of the link connections 16, the

. cross-head will be given a movement slightly arcuate, which will in turn, through the crank and block on the opposite side of the cross-head, give to the secondary or agitator shaft and the agitator carried thereby, a reciprocating movement, such as is desired in a machine of this character, which is clearly illustrated in Figure 1 of the drawlngs.

The numeral 20 designates an agitator mounted on the agitator shaft and located within the receptacle. agitator mounted with the legs projecting upwardly from the spider, but this is not essential.

The casing 1 is made of two parts which when brought together as disclosed in Figure 4, will entirely house the mechanism, the power shaft entering at one side and the agditator shaft projecting from the opposite si e.

Having thus described my' invention, I claim and desire to secure by Letters Patent 1. A mechanical movement consisting of a power shaft and a secondary shaft, a crank on the end of the power shaft and adapted to be rotated thereby, a block attached to the end of the crank, and a crosshead in which said block moves with a slidable movement, a like block also slidably located on the opposite side of the crosshead, a crank carried by the secondary shaft and attached to the last named block, and a pair of positioning links pivotally mounted at one end and at their opposite ends to opposite points of the cross head, whereby the rotation of the power shaft will cause the secondary shaft to move with an oscillatory movement,

I have shown the 2. In a mechanical movement, a power shaftya crank carried there-by, a block carried by the crank, a cross-head in which the block is slidably mounted, a second block also slidably mounted in the opposite face of the cross-head, a crank to which said second block is attached, and a secondary shaft on which said crank is mounted and keyed, with two parallel links pivot'ally mounted atoneof their ends and at their opposite ends to the cros s heathhwhereby rotary movement of the powefshaftwill be converted into oscillatory movement of the secondary shaft.

3,111 a deviceof the character described, a cross-head having projections on opposed sides and grooves on its opposed faces, av pair of blocks slidably mounted in the grooves, cranks to which said blocks are at tached, one of said cranks being-mounted on and rotated by a power shaft, and the other crank being mounted on and adapted to actuate asecondary shaft, and links secured to the cross-head projections, whereby the rotation of the power shaft will oscillate the secondary shaft. r I v In testimony whereof I afix my signature.
